Someone should make a Slam Dunk basketball game.

I don't think such a game would even do well in Japan. Let's face it, Slam Dunk WAS huge there, but the fanbase is dated. If the author starts up that Slam Dunk followup he's mentioned once or twice, then yeah, it'd be a great idea. But as it stands now, probably wouldn't.
